and fi few species ocrumriG; also (probably iiiiroJuced) in S. America, five are tropical, both 

 in the New aud the Old ^Yorld, five are "chiefly American and Andine or estratropical, of 

 which two are also represented in the monntains of tropical Asia, two belong chiefly to the 

 extratropieal flora of both hemispheres, and only four are endemic in Australia. 



The Order is closely allied to Solanece, difi'erinp chiefly in that irregidarity of flower 

 which connects it with Bipwniace^, Jcanthacece, Verhenacew, aud others of the personate 

 orhilabiate group, and which is evidenced in Scrojilndarinem, either by the didynainy of 

 tlie stamens or by the bilabiate estivation of the corolla, or, in most cases, by both cha- 

 racters.
